Wheel brush

This application claims priority to Chinese Patent Application No. 201511006571.7, filed on Dec. 29, 2015, which is hereby incorporated by reference in its entirety.

The present invention relates to a burring brush, and in particular to a wheel brush convenient to change bristles.

In an aluminum alloy wheel production process, removal of burrs after machining is a very important working procedure. If an ideal effect cannot be achieved, it will often seriously affect the qualification rate of a subsequent coating working procedure. In order to meet the standard requirements, currently almost all manufacturing enterprises increase the rotation time of burring brushes on special devices, which seriously affects the service lives of the burring brushes. Therefore, it is necessary to realize convenient change of bristles of the burring brushes in order to save the production costs and achieve the repeated use of other components such as a base plate and the like.

An object of the present invention is to provide a wheel burring brush in which bristles can be quickly changed, and other components except the bristles can be repeatedly used.

To achieve the object described above, a technical solution of the present invention is as follows: a wheel brush is composed of a base plate, wing nuts, gaskets, springs, pull rods, fixing pins, iron sleeves and bristles. The bristles are adhered to the interior of one iron sleeve to form a bristle unit.

In one bristle unit, the upper end of the pull rod is welded to the lower side of the fixing pin; the two ends of the spring are welded to and fixed on the lower side of the fixing pin and the upper side of the gasket, respectively; the gasket sleeves the pull rod; the wing nut is welded to the lower side of the pull rod; and the wing nut, the gasket, the spring, the pull rod and the fixing pin form a chuck.

The bristle unit is fixed on the upper side of the base plate, and two guiding lugs of the fixing pin of the chuck are fixed to the lower side of the base plate after matching an annular groove in the iron sleeve.

Two anti-rotating lugs are arranged on the upper side of the iron sleeve and match two lug slots in the base plate. Two symmetrical guiding slots are formed in the lower side of the iron sleeve and match the two guiding lugs of the fixing pin.

During actual use, when the bristle unit is to be mounted, the iron sleeve of the bristle unit is placed on the upper side of the base plate, the two anti-rotating lugs are made to correspond to the two lug slots in the base plate, and the chuck is inserted from the lower side of the base plate; after the gasket is fixed in a counter bore in the lower side of the base plate, the wing nut is continuously pressed upwards, so that the spring is tensioned, and the two guiding lugs of the fixing pin come into contact with the bottom ends of the guiding slots in the iron sleeve; and after the wing nut is rotated by 90 degrees, the bristle unit can be locked; when the bristles are to be changed, only the wing nut needs to be rotated, and when the positions of the two guiding lugs of the fixing pin correspond to the positions of the two guiding slots in the iron sleeve, the fixing pin can be bounced out of the iron sleeve under the action of the spring.

When the wheel brush provided by the present invention is used, the bristles can be changed quickly, and other components except the bristles can be repeatedly used, so that the production costs can be reduced, and characteristics of advanced technique and simple structure are achieved.

In the figures, numeric symbols are as follows: 1 -base plate, 2 -wing nut, 3 -gasket, 4 -spring, 5 -pull rod, 6 -fixing pin, 7 -iron sleeve, 8 -bristle, 11 -lug slot, 61 -guiding lug, and 62 -anti-rotating lug.

In the following, the details and working conditions of a specific device provided by the present invention are described in detail in combination with figures.

A wheel brush is composed of a base plate 1 , wing nuts 2 , gaskets 3 , springs 4 , pull rods 5 , fixing pins 6 , iron sleeves 7 and bristles 8 . The bristles 8 are adhered to the interior of one iron sleeve 7 to form a bristle unit.

In one bristle unit, the upper end of the pull rod 5 is welded to the lower side of the fixing pin 6 ; the two ends of the spring 4 are welded to and fixed on the lower side of the fixing pin 6 and the upper side of the gasket 3 , respectively; the gasket 3 sleeves the pull rod 5 ; the wing nut 2 is welded to the lower side of the pull rod 5 ; and the wing nut 2 , the gasket 3 , the spring 4 , the pull rod 5 and the fixing pin 6 form a chuck.

The bristle unit is fixed on the upper side of the base plate 1 , and two guiding lugs of the fixing pin 6 of the chuck are fixed on the lower side of the base plate 1 after matching an annular groove in the iron sleeve 7 .

Two anti-rotating lugs are arranged on the upper side of the iron sleeve 7 and match two lug slots 11 in the base plate 1 . Two symmetrical guiding slots are formed in the lower side of the iron sleeve 7 and match the two guiding lugs 61 of the fixing pin 6 .

During actual use, when the bristle unit is to be mounted, the iron sleeve 7 of the bristle unit is placed on the upper side of the base plate 1 , the two anti-rotating lugs 62 are made to correspond to the two lug slots 11 in the base plate 1 , and the chuck is inserted from the lower side of the base plate 1 ; after the gasket 3 is fixed in a counter bore in the lower side of the base plate 1 , the wing nut 2 is continuously pressed upwards, so that the spring 4 is tensioned, and the two guiding lugs 61 of the fixing pin 6 come into contact with the bottom ends of the guiding slots in the iron sleeve 7 ; and after the wing nut 2 is rotated by 90 degrees, the bristle unit can be locked; when the bristles 8 are to be changed, only the wing nut 2 needs to be rotated, and when the positions of the two guiding lugs 61 of the fixing pin 6 correspond to the positions of the two guiding slots in the iron sleeve 7 , the fixing pin 6 can be bounced out of the iron sleeve 7 under the action of the spring 4 .
